Is it better to use the assisted/control or SIMV with pressure support mode of ventilation in patients who fail weaning?

A Draeger ventilator, the Evita 4, also provided this mode. They found that, with MMV, fewer mechanical breaths were required as compared to SIMV, without any change in CO 2 values or oxygen levels.

Our results demonstrate that NAVA is as effective as SIMV (PC) PS in short-term use; in this population of infants, this mode of ventilation can be considered when selecting a mode of ventilation ...

Does the Ventilator Mode Matter? One of the underlying controversies within pediatric critical care centers around the mode of ventilation, and studies demonstrate substantial variation in the ...
